INSTALLATION

Continued

15.If gas connections have been made and checked, replace fireplace floor assembly in fireplace. Feed flexible gas supply line into fire- place base area while replacing fireplace floor assembly. Make sure the entire flexible gas line is in fireplace base area. IMPORTANT: Do not pick up fireplace floor assembly by burners. This could damage burners. Only handle base by grates. Note: Be careful of all wires and components on underside of floor assembly.

16.Reattach fireplace floor assembly with screws removed in step 3 of Removing Fireplace Screen and Floor Assembly, page 8.

Note: Discard the remaining hardware items. After assembly, make sure all wires are completely clear of blower wheel.

17.Install logs (see Installing Logs, pages 21 through 23) and fire- place screen (see Installing Screen, page 24).

WARNING: Failure to position the parts in accor- dance with supplied diagrams or failure to use only parts specifically approved with this heater may result in damage or personal injury.

WARNING: A qualified service person must con- nect fireplace to gas supply. Follow all local codes.

If any of the original wire as supplied with the appliance must be replaced, it must be replaced with 105˚C wire or it's equivalent.

Operating the Blower

After final installation of your fireplace, light your gas appliance with the blower off. After about 15 minutes, turn the blower on to deliver heated air at the top louvers. The blower features a variable control which allows you to select the speed you desire. In the OFF position, the blower will not operate. In the ON position, the blower will start when the thermostat senses a sufficient increase in firebox temperature (approximately 10 to 20 minutes depend- ing on heat setting).

Your gas logs and thermostat blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases.

It is safe to operate fireplace with blower turned off. However, the blower helps distribute heated air from the fireplace.

Note: Periodically check the louvers of the firebox and remove any dust, dirt, or other obstructions.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: A qualified service person must con- nect fireplace to gas supply. Follow all local codes.

WARNING: For propane/LP units, never connect fireplace directly to propane/LP supply. This fire- place requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.
